1. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 1 Assignment 1 Creating a Heart

2. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 2 Step 1 In this lab, you will be creating a love-heart by using a standard NURBS sphere, and tweaking its control points. Start off with a clean blender Select A twice to select all the elements Click X to erase all of the selected objects on the 3D window Add a NURBS sphere to a new scene. NURBS spheres are located in the toolbox SPACE  ADD  SURFACES  NURBS Sphere If you are not in the top view, switch to top view using [NumPad 7] If you are not in wireframe view press [Z] to see the object in wireframe

3. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 3 Before you continue, you can scale up the sphere so that it fills the better part of your screen by pressing [S], moving your mouse and left-clicking when you're satisfied. Your object should look like as follows at this stage. It is the top view of the sphere in wireframe form with all vertices selected

4. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 4 Step 2 Go to frontview NumPad [1] enter editmode by pressing [TAB]. Deselect all vertices by pressing [A]. Use border select [B] to select the middle vertices in the top-row of the control points. The figure shows which area to select

5. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 5 Step 3 If you switch to top view by pressing [NumPad 7], you can see that you have actually selected a couple of vertices that were hidden from your view in the front view. Make sure you are back to front view Deselect all vertices if any is selected using [A] Using box-select [B] in front-view selects all vertices within the box.

6. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 6 Step 4 Once the vertices are selected in step 3, the next step is to enter grabmode [G], and move the three selected vertices slightly downwards. Switched from wireframe to Shaded view by pressing [Z] to view this better This will create a nice, smooth bump in the sphere as shown below

7. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 7 Step 5 Deselect all selected vertices with [A]. (This is a step that you have to make each time in the remaining steps of this tutorial). Select the three vertices in the top- left and the three in the top-right, and scale them a bit by using the scaling mode [S] This way the top becomes a bit wider. When you are satisfied with it, use the grabber [G] to move the vertices up a bit.

8. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 8 Step 6 The heart is starting to look good Make the bottom more pointy by box-selecting [B] the vertices at the bottom and using the grabber [G] to move them downward.

9. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 9 Step 7 The heart looks better; however, the bottom is still a bit blunt. Make it more pointy by box-selecting [B] the middle vertex at the bottom and using the grabber [G]to move them downward.

10. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 10 Step 8 Now, in the frontview our heart looks just fine, but when you switch to sideview [NumPad 3], you will see that you have drawn a mighty fat heart! Switch to side view [NumPad 3] to see the thickness of the heart

11. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 11 Step 9 Select all vertices (press [A] twice), scale everything in the y-dimension. To do this, enter scaling mode [S] and then press [Y] and make it thinner. This will lock the scaling to only one dimension.

12. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 12 Follow the steps below to paint the heart red Click on shading button or press F5 Click on material button Click on Add New Button

13. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 13 Click on the box next to the “Col” button to see selection of colors Select red

14. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 14 Step 10 Add a camera to the scene (Space  Add  Camera) Select the Camera first and then do [Shift RMB] to select the heart (both should be selected now) Press [Ctrl T] (choose track to constraint) to make the camera track the object

15. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 15 Step 11 Add a spot light to the scene (Space  Add  lamp-> Spot) Select the Lamp and the heart together [Shift RMB], and press [Ctrl T] (choose track to constraint) to make the spot lamp track the object

16. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 16 Step 13 Rotate the heart to face the camera [Press R twice ] and turn it. If you want you can also add another light to make it look better when rendering is done

17. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 17 Step 14 You can render the scene (Press F12) to see how it looks like. You should have something like the following without the blue plane.

18. Sahar Mosleh & Ahmad R. Hadaegh California State University San Marcos Page 18 Step 16 Press F1 and save the file under your CS306 directory in your H drive
